What kind of hairstyle looks good on a 17 year old American girl? Right now, I have shoulder length hair, and I’d really like to bob it but the sides are too short. My hair is a medium shade of brown with a blonde streak in the back and it’s easy to get straightened. Usually I just do a half-up/half-down thing, but I’m sick of it. Since I’m going to the salon this week, I am thinking for a change.
